Primary scope : Effectiveness evaluation
12. Main objective(s)
What is the main objective of the study?
The main objective of the study is to evaluate the impact of the implementation of risk minimisation measures (RMMs) (DHPC and updated SmPC) on the prescription behaviour of physicians in Germany.
Are there primary outcomes?Yes
• indication for flupirtine
Description of proportion of patients with
• pre-existing liver disease/alcohol abuse
• pre-treatment with/ contraindications for NSAIDs and weak opioids
• duration of treatment
• single and repeated flupirtine prescriptions
• concomittant use of hepatotoxic drugs
• liver function test monitoring
Are there secondary outcomes?Yes
The secondary objective of this study is to:
• Compare the length of treatment or proportions observed for each of the objectives listed above in the patients initiating flupirtine since implementation of RMMs to treatment length or proportions observed in the patients treated with flupirtine before the implementation of RMMs.
13. Study design
What is the design of the study?
Drug utilisation study
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
For all patients a minimum follow-up of at least one month after exposure start date will be taken into account. Patients will be followed over the individual available follow-up time ranging from a minimum of 1 month up to a maximum of 13 months.
15. Data analysis plan
Please provide a brief summary of the analysis method
The data will be analysed separately by data source (IMS® Disease Analyzer and IMS® LRx).
The statistical analysis will be done descriptively and performed separately by database, per physician panel and per observational period. All analyses will be stratified by incident and prevalent users. Missing values will be reported as missing and no imputation will be conducted. Descriptive tables will be made for all variables. Confidence intervals (95%) around estimates before and after the implementation minimization measures will be calculated. For comparison of patients initiating on flupirtine since the implementation of RMMs with patients treated with flupirtine before the implementation appropriate statistical tests will be used.
